132 SOME BIRDS OF SOUTH AFRICA 



Greenshank zigzagging about here and there amongst 

 them, feeding in his hap-hazard way. Another Egret 

 joins them, moving over the water with a soft, owl-Hke 

 tiight, and when he has settled he keeps his long neck 

 stretched out in a somewhat ungainly attitude, not at 

 all resembling the graceful pose in which he is often 

 depicted. Something startles the Greenshank, always 

 the wariest of birds, and he flies u[) with four or five

Another Curlew alights, and stands immovable ; he 

 remains so for at least five minutes, apparently absorbed

 within the limit of his keen si^ht, then, as though in 

 apology for having been so long in commencing to feed, 

 he seems to recollect himself, and puts his long curved 

 bill down a little way towards the shallow^ water in which 

 he is standing, then draws it up again. He is in no 

 hurry, he can easily wait another two or three minutes. 

 So a little while later he slowly puts it down again, this 

 time so as to almost touch the water, and then — com- 

 mences to feed? — Oh no, he only wanted to find out
